Even if there *are* specific professions/occupations that show a high incidence of PD, this does not mean that there is an environmental trigger. There are reasons people choose or end up in various occupations. These could be related to differences in personality, ethnic or social background, group dietary habits, use of tobacco and alcohol, etc. which could in turn be related to occurence of the disease. Why you do not receive a copy of your own post: this one I can answer without waffling. The Parikinsn list runs on listserv software at the U. of Toronto. This is a very old (in Internet terms) piece of software. In those days, Internet bandwith was very expensive, and some people even paid by the number of messages they sent and received. To cut down on the use of bandwith, listserv does not send you a copy of your own post, on the theory that you know what you said and your mail program keeps a copy anyway. Most mailing-list software does not bother with this anymore. Besides, it never really worked. When someone did not see their message, they would send in another 10 copies to the whole list, after which 20 other folks would send messages to the whole list telling the poor guy to stop sending his message already. Thereby using a lot more bandwith. ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
